Evaluation of Water Resource Utilization Efficiency and Its Regional Difference in China
摘要
Abstract
Crisis of water resource and deterioration of water environment have become an increasingly severe problem in China, so it is quite stringent to carry out scientific and reasonable evaluation of water resource utilization efficiency and discussion of related influencing factors in regional difference in China. In this paper, under the framework of total-factor productivity, environmental factors are integrated into efficiency analysis. By use of data envelopment analysis model and adoption of the statistic data in provincial level, regional water resource utilization efficiency from 2000 to 2011 is calculated with capital, labor force and water consumption as input and GDP and wastewater discharge as output. The results show that from the temporal perspective, differences in water utilization efficiency of the provinces in China have been widened increasingly year by year, and from the spatial perspective, there exist obvious regional disparities among East China, Central China and West China. Further results show that such factors as industrial structure, economic development level, water resource endowment and water infrastructure input have significant influences on regional water resource utilization efficiency, while water price has no much effect on it.关键词
